25
When is extraction of an INCISOR indicated?
Malocclusion Root infection Loss of opposite tooth Abscesses
26
When is extraction of a CHEEK TOOTH indicated?
Never- as staggered, so extraction affected more than 1 opposing teeth.
27
List the likely causes of diarrhoea in a YOUNG rabbit.
Increased gastric pH- allowing Clostridial entry, | Tyzzer's disease
28
What is the aetiological agent in Tyzzer's disease?
Clostridium piliforme
29
List the likely causes of diarrhoea in an ADULT rabbit.
Increased CHO in diet- causes bacterial overgrowth Sudden dietary change Stress/concurrent illness A/b's- especially penicillin orally
30
What are the causes of gastric stasis in the rabbit?
1. Mechanical obstruction = dehydrated ingesta secondary to chronic dehydration, FBs or infiltrative lesions 2. Abnormal function of myenteric neuronal/gastric smooth muscle Primary = anorexia, poor diet, post-surgical adhesions, lack of exercise, toxin ingestion Secondary = pain, environmental stressors, change in environment, loss of companion, extreme temp/humidity etc.
31
What are the clinical signs of gastric stasis caused by a mechanical obstruction?
Acute anorexia and no faeces, with a rapidly depressed collapsed rabbit. Tympanic abdomen and shock.
32
What are the clinical signs of gastric stasis caused by abnormal myenteric neuronal/smooth muscle function?
Gradual reduction in appetite and the size/amount of faeces, with gradual depression and dehydration.
33
Describe how you would treat gastric stasis caused by abnormal function.
MEDICAL MANAGEMENT: | Fluids, nutritional support, analgesia, pro-kinetics e.g. ranitidine, exercise to stimulation bowel movements.
34
Describe how you would treat gastric stasis caused by a mechanical obstruction.
SURGICAL removal, with prior attempt at stabilisation.
35
What are the clinical signs of upper respiratory disease in rabbits?
``` Sneezing Snoring Dyspnoea Ocular discharge Conjunctivitis Dacryocystitis Nasal discharge (including "dirty hankies") ```
36
What are the clinical signs of lower respiratory disease in rabbits?
``` Dyspnoea Cyanosis Anorexia Depression Lethargy Pyrexia Hypothermia Pulmonary rales Increased respiratory efforts ```
37
Which parasite causes "walking dandruff"?
Rabbit fur mite- Cheyletiella parasitovorax
38
Which parasite causes otitis externa?
Rabbit ear mite- Psoroptes cunculi
39
Which agent causes rabbit syphilis?
Treponema cuniculi
40
What are the clinical signs of syphilis in the rabbit?
Crusting at the nose and perineum
41
How is syphilis treated in the rabbit?
Penicillin injections 1x/week for 3 weeks
42
What are the risk factors for plantar pododermatitis?
Obesity Inactivity Poor sanitation Breed disposition- Rexes (no guard hairs)
43
List the potential causes of urine scald in the rabbit.
``` UTI Spinal lesions- cant groom itself Encephalitozoonosis Urolithiasis/hypercalcinuria Obesity Renal failure Malformation Ectopic ureters Conditions that prevent normal grooming e.g. dental disease ```
44
What is the causative agent of encephalitozoonosis?
Encephalitozoon cuniculi
45
Describe the pathogenesis of encephalitozoonosis.
Infects WBCs -> cell ruptures releasing spores into the extracellular fluid -> affects brain/kidney/eye
46
Which organs does encephalitozoonosis affect?
Brain Kidney Eye
47
What are the clinical signs of encephalitozoonosis?
``` Head tilt Torticollis Hindlimb paresis Paralysis Tremors Convulsions Urinary incontinence Cataracts Lens-induced uveitis ```
48
How is encephalitozoonosis diagnosed and treated?
Diagnosis: paired serology (IgM = acute, IgG = chronic), PCR detects spores in urine/faeces, endoscopic kidney biopsy Treatment: oral fenbendazole daily for 4 weeks
49
What is the ideal diet for a rabbit?
78% hay/grass (ad-lib, but at least own body weight per day) 20% leafy greens (2 handfuls containing at least 5 different types) 2% pellets (twice daily, good way to monitor appetite)
50
Why is fibre important for rabbits health?
Wears teeth correctly Provides energy (40% energy from VFAs) GI health- 'scratch' factor Allows normal herbivore behaviour- welfare
51
Which vessels can be used to place an intravenous catheter?
Marginal ear vein Lateral saphenous vein (but v wobbly) Cephalic vein (if big enough bunny)
52
Which sites can be used for intraosseous catheterisation?
Proximal tibia Proximal femur Proximal humerus
53
What is the maintenance fluid rate for rabbits?
4ml/kg/hour (approx 100ml/kg/day)
54
What is the gold standard method of urine collection in the rabbit?
Catheterisation (also free catch and cystocentesis)
55
Where can you give an IM injection?
``` Dorsal lumbar muscles Quadriceps muscles Semimembranous muscle Semitendinosus muscle (only suitable if ```
56
Which sites can be used for blood sampling in the rabbit?
Marginal ear vein Lateral saphenous vein Jugular vein Cephalic vein
57
What is the normal pH of rabbit urine?
8.2
58
What is the common cause of pink rabbit urine?
Due to poryphrin (from dandelions, stress)
59
What causes increased albumin in the rabbit?
Dehydration Hypovolaema Prolonged hyperthermia
60
Which antibiotics are safe for rabbits?
TMPS Fluoroquinolones Metronidazole Tetracyclines
61
Describe how to prevent suture reactions in rabbits.
Its common to get adhesions/pus. - use Ca-channel blocking agent 'veropamil' or NSAIDs - use hydrolytically degrading suture materials (NOT catgut)
